function/macro ergonomics

[PierreR]

It looks like the suggested syntax for function/macro using the _ has some limit:

For instance it doesn't seem to be possible to do:

_stripId: {
    #in: string
    let List = strings.Split(#in, "/")
    List[len(List)-1]
}

// KO
test: _stripId & {_, #in: "hello/world/you"}

In that case, it looks like you need to use a out field which is less ergonomic:

_stripId: {
    #in: string
    let List = strings.Split(#in, "/")
    out: List[len(List)-1]
}

// OK
test: (_stripId1 & {#in: "hello/world/you"}).out

Hmm, @PierreR this appears to be a bug. I will raise an issue and link to it from here.
